Compare any two graphics cards:
GeForce GTS 450 1GB vs GeForce GTX 965M
IntroThe GeForce GTS 450 1GB has a GPU core speed of 783 MHz, and the 1024 MB of GDDR5 memory is set to run at 902 MHz through a 128-bit bus. It also features 192 Stream Processors, 32 Texture Address Units, and 16 ROPs.Compare all that to the GeForce GTX 965M, which features a GPU core clock speed of 944 MHz, and 2048 MB of GDDR5 memory set to run at 1000 MHz through a 128-bit bus. It also is comprised of 1024 SPUs, 64 TAUs, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GTX 965M should in theory be a little bit superior to the GeForce GTS 450 1GB in general. (explain)
Texel RateThe GeForce GTX 965M should be much (more or less 141%) more effective at AF than the GeForce GTS 450 1GB. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce GTX 965M is a better choice, by a large margin. (explain)
Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be transferred over the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
